1. 1. Evidence for "liveness" in face biometrics

   Författare :Klaus Kollreider; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion estimation; Optical flow of lines; Quangles; Object detection; OFL; Liveness detection; Anti-spoofing measures; Structure tensor; Quantized angle features; Face biometrics;

   Sammanfattning : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. LÄS MER

3. 2. Verifying Absence of ∞ Loops in Parameterized Protocols

   Författare :Mayank Saksena; Bengt Jonsson; Ahmed Bouajjani; Uppsala universitet; []
   Nyckelord :formal methods; verification; model checking; infinite-state systems; regular model checking; liveness; graph transformation;

   Sammanfattning : The complex behavior of computer systems offers many challenges for formal verification. The analysis quickly becomes difficult as the number of participating processes increases. A parameterized system is a family of systems parameterized on a number n, typically representing the number of participating processes. LÄS MER

4. 3. Expression in Live Coding: Gestural Interaction for Machine Musicianship

   Författare :Georgios Diapoulis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; music perception; live programming; liveness; music interaction; live coding; music information retrieval; gestural control; musical interfaces; expressive interaction; music performance;

   Sammanfattning : This thesis is centered on the performance practice of musical live coding, which can be described as on-the-fly decision-making for computer music performance and blurs the lines between programming languages and computer interfaces. I specifically focus on live coding as a human activity based on serial skilled actions, and I discuss how we can interact gesturally with interfaces that are modified dynamically. LÄS MER

5. 4. Going Live : Collaborative Video Production After Television

   Författare :Arvid Engström; Oskar Juhlin; Elizabeth Churchill; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Video; live; production; broadcasting; mobile; amateur; liveness; interaction design; collaboration; participatory media; Man-Machine-Interaction MMI ; människa-maskin-interaktion MMI ;

   Sammanfattning : This thesis explores social and creative practices that emerge with new mobile video technology. The work frames a design space that spans across both the social and technical domains. LÄS MER
